After entering my eBat username and password, and clicking 'login test', after trying for some seconds, BOM pops-up an error message as per attached BOM_login_fail.png (with no clue as to why it failed). It then opens a page in Firefox (v72.0.2 64-bit): file:///C:/Users/Daniel/AppData/Local/Temp/scratch.html that asks for my eBay credentials (attachment Scratch_request.png). If I fill them in there, it then takes me to a real eBay login page (.uk) where I again must enter my username and p/word.
PS: I tried to attach two screen-shots, but only the last one's name is displayed in the 'Attachments:' (note plural) box.
The BOM-version that is available here, is not working anymore.
You will find an alternative fork here:

Thanks Icke. I had a look at that site, but there was no compiled .exe for Windows, so I'll just stick with Gixen until something better comes along.
